Trailer Suspension Parts with Leaf Spring Replacement System

Looking for a smoother, calmer tow? A leaf spring replacement system uses slipper springs for better control, and kits are available with shock absorbers. Match spring rating to your axle—use 7K with 7K axles; 8K can work on 3" tubes but rides more aggressive and may need new 3" tie plates or U-bolts. These systems don't include wet bolts, and with slipper springs only one wet bolt fits per leaf spring; check hanger areas for any plumbing first.
They generally do not include wet bolts, and slipper spring layouts use fewer greasable points. You can add wet bolts at the main spring eye to help keep water and rust out. Use a quality high-stress grease during assembly to maintain smooth movement.
